Study of Cloud Computing Security Based on Private Face Recognition

Supporting study of a method to solve cloud computing security issue with private face recognition. The method has three parts: user part provides face images; cloud initialization part has a face subspace and templates database; cloud private matching identification part contains the core algorithm of the method, comparing two encrypted numbers under double-encrypted conditions. The experimental results show the method can ensure that cloud neither know user´s real face data, nor the face private matching identification result, to make user´s face data secure, we develop a credible, efficient, low-complex method to guarantee cloud computing security.
